A design example for a bandpass filter is shown below:
Assume the system design requires a bandpass filter with f
O
= 1kHz and Q = 50. What needs to be calculated are
capacitor and resistor values.
First choose convenient values for C
1
, R
1
and R
2
:
C

= 1200pF
2R

= 30k
Then from
Equation (11)
,
From
Equation (12)
,
From the above calculated values, the midband gain is H
=
R
/R
= 100 (40dB). The nearest 5% standard values have
been added to
Figure 15
.
4.5 PULSE GENERATORS AND OSCILLATORS
A pulse generator is shown in
Figure 16
. Two diodes have
been used to separate the charge and discharge paths to
capacitor C.
